Figure 1. In vitro expansion and main phenotypes of CIK cells derived from donors (n = 10).
Differential expression of three main phenotypic subsets of CIK cells over in vitro culture are shown for identification of CIK cells, CD3/CD56 (A), T cell associated immune receptors, CD3/CD4/CD8 (B), and major activating receptors of CIK cells, CD3/NKG2D (C). Flow cytometric analysis was performed over expansion periods on day0, day7, day14, and day21. Each representative picture was accordingly shown on the right panel.
